How can I cancel a web service call?

[HOFFMANN Camille]

Hi,

I’m currently working on a simple web service working with Axis 1.2.1 
and Tomcat 5.
This web service is working perfectly but I have a problem with long 
running calls.
In fact I would like to know how I can cancel a call which is taking to 
much time?

Did anybody have this problem before or know how to do this?

Thanks,

Camille
